Class featuresSpellcasting: At 2nd level, and every other level thereafter, a Master of Automata gains new spells per day (and spells known, if applicable) as if he had also gained a level in a spellcasting class to which he belonged before adding the prestige class level. He does not, however, gain any other benefi t a character of that class would have gained (such as the bonus feat sometimes gained by a wizard). If he had more than one spellcasting class before becoming a Master of Automata, he must decide to which class to add each level for the purpose of determining spells per day and spells known.

Craft homuculus: As the Artificer class feature, except that the spells need not be emulated. If the Master of Automata already has the Craft homunculus class feature, the homunculi created may have as many Hit Dice as the Master of Automata.

Guardian Automaton: A Master of Automata’s main strengths lie in the powerful and versatile constructs he creates, known as Guardian Automata. A Guardian Automaton is a medium construct, humanoid in shape, crafted by the Master of Automata. The Master of Automata may only have a limited number of Guardian Automata active at any one time, as shown on the table. More than this number can be created, but the process of deactivating one construct and activating another requires two uninterrupted hours of work in a workshop.Creating a Guardian Automaton takes one week, and costs <to be confirmed>. It requires a reasonably well-equipped workshop. A Guardian Automaton has two Hit Dice per class level of the Master of Automata; the construct does not automatically gain new Hit Dice when the Master of Automata gains a level, but one day’s tinkering is sufficient to upgrade all the Guardian Automata.A Guardian Automaton has certain special abilities, chosen by the Master of Automata. At each new level, the Master of Automata may select a new ability from the list indicated on the table above to add to his Guardian Automaton. If he has multiple Guardian Automata, he may select a different ability for each one. A Master of Automata may, if he desires, add an ability from Menu A instead of an ability from Menu B, or an ability from Menu A or B instead of an ability from Menu C. The abilities are added in the same day’s tinkering that upgrades the constructs’ Hit Dice.

Ability score increase: A +2 permanent increase to any one of the Guardian Automaton’s ability scores. This ability may be taken multiple times.Blades: A short blade concealed in each arm of the construct. The Guardian Automaton may make one attack with each blade at its full attack bonus as a full attack action. Revealed and concealed as a swift action. 1d6, 19-20/x2, slashing.Death throes: If the Guardian Automaton is ever destroyed, it immediately explodes in a conflagration that deals 1d8 points of damage per class level to everything within a 30 foot radius (Ref half, DC 10 + class level + creator’s INT bonus)Fast Healing: The Guardian Automaton gains Fast Healing 1. This ability may be taken multiple times; each time, increase the amount of Fast Healing by 1.Fighter bonus feat: The Guardian Automaton gains a feat from the Fighter bonus list. This special feature may be chosen up to 5 times per Guardian Automaton. Each time it is selected, choose a different feat.Gun: Concealed gun. Revealed or concealed as a swift action. Use stats from d20 Modern, any small arms are acceptable.Humaniform: The Guardian Automaton can pass as human to all non-magical detection. In appearance it is perfectly human, and all x-rays and other sensors read it as human.Improved Grab: The Guardian Automaton gains the Improved Grab special ability with any built in melee weaponImproved Speed: The Guardian Automaton’s speed becomes 10 foot per round per class level, minimum 30.Intelligence score: You grant the Guardian Automaton an intelligence score of up to your class level plus your intelligence bonus. If desired, you can give it a lower intelligence score. This also grants it skill points as normal.Invisibility: The Guardian Automaton remains invisible even when it attacks. This ability is continuous, but the Guardian Automaton can suppress it as a free action.Jet propelled flight: The Guardian Automaton can change configuration to a rapid, fixed-wing form. This transformation takes one round. In this form it gains a fly speed of 2000 feet per class level, with poor manoeuvrability, but loses all other movement types and attacks.Life support: The Guardian Automaton can deploy a capsule capable of carrying up to two medium creatures in cramped conditions. The deployment takes one round, but may be performed in the same round as the transformation to the jet propelled form. This capsule can support life for up to 10 hours, no matter the outside conditions.Long distance communication: The Guardian Automaton is capable of communicating mentally with the Master of Automata regardless of distance, as long as both remain on the same plane.Natural Armour: You reinforce the Guardian Automaton, granting it a natural armour score equal to your class level.Recording capabilities: The Guardian Automaton can record up to 8 hours of audio and visual footage. This can be downloaded to a hard drive or played back directly.Speech: The Guardian Automata gains the ability to speak one language that you know. This special ability may be taken multiple times; each time it is selected, choose a different language for it to apply to.Spell imbued: You imbue the Guardian Automaton with a single spell, of a maximum level depending on which level of ability you select. The Guardian Automaton can cast this spell once per day per two class levels, minimum one. This special ability may be taken multiple times; each time it is selected, choose a different spell for it to grant.Swim Speed: The Guardian Automaton has a swim speed equal to its land speed, with all the benefits thereof.Taser: Use stats from d20 Modern.Winged flight: You attach wings to the Guardian Automaton, granting it a fly speed equal to twice its land speed, with average manoeuvrability. This is not incompatible with the Humaniform ability, but the wings will not be hidden, necessitating either bulky clothes or risking spreading stories of angels.

Proficiencies: A Guardian Automaton is proficient with all simple and martial weapons.

Composite Plating: The plating used to build a Guardian Automaton provides a +2 armour bonus. This plating is not natural armour and does not stack with other effects that give an armour bonus (other than natural armour). This composite plating occupies the same space on the body as a suit of armour or a robe, and thus a Guardian Automaton cannot wear armour or magic robes. Guardian Automata can be enchanted just as armour can be. The automaton must be present for the entire time it takes to enchant it. A Guardian Automaton qualifies for the Warforged body feats.
